TY - JOUR PY - 1976// TI - A disaggregate modal-split model for work trips involving three mode choices JO - Transportation research record A1 - Ganek, Jeffrey A1 - Saulino, Raymond SP - 25 EP - 29 VL - 610 IS - N2 - This paper describes a disaggregate mode choice model with three travel modes: drive alone, car pool, and transit. A number of alternative model specifications were tested and the results analyzed. In general, the coefficients of in-vehicle time, out-of-vehicle time, and costs agree closely with the results of similar studies. Estimated coefficients of variables not included in previous logit model studies are also presented: Of these convenience, comfort, and flexibility influenced mode choice but mode unreliability and household income did not. Work location, cars per driver, and sex were the only socioeconomic variables for which statistically significant coefficients were found. Coefficients and models were also estimated for various subpopulations of commuters. The determinants of mode choice for CBD workers were different from those of non-CBD workers. differences in the cost and time coefficients among travel corridors and income classes were also examined. The estimated models were validated by successfully predicting the mode choices of the commuters for whom the model were estimated, of other commuters, and, finally, of commuters for whom changes in the level of service were made available.
